Head lice are insects (wingless) whose domicile is the human scalp. They feed on human blood and man is the only known host of these insects. Many individuals think that head lice and body lice are one and the same thing. Nothing could be further from the truth. The two are different sub-species with the distinction between them being drawn from their modus operandi. The body louse attaches its eggs to the clothing of its host, whilst the head lice attaches its eggs upon the scalp of its host. These lice spend their entire life cycle on the scalp of the host.
A head lice will typically feed about five times during the day. They inject the skin using their proboscis, drain their saliva into the host and then draw blood from the host. Unlike other parasites however, head lice do not attach themselves to the body of the host. The have short stubby legs, are wingless, and can hardly move on a flat surface. As a result of consuming the host’s blood they become rust colored – it is this color that is used to identify them as lice. This is basically how this six legged, no winged insect operates.
